Answer:
T=120(P+B)
Step-by-step explanation:
If a pack holds 120 tissues, then P packs will hold (P×120) tissues
This implies,
1 pack : 120 tissues
P packs : 120P tissues
Also, if a box holds 120 tissues, then B boxes will (B×120) tissues
This implies,
1 box : 120 tissues
B boxes : 120B tissues
Writing a formula in terms of T, where T is the total we obtain,
T=120P +120B
Using the idea of factorization we obtain
T=120(P+B)
Answer:
- a) AB = 10 units
- b) Midpoint is (2, 6)
===================
<h3 /><h3>Given</h3>
- Points A( - 1, 10) and B(5, 2)
<h3>To find</h3>
- a) The length of AB
- b) The midpoint of AB
<h3>Solution</h3>
a) Use the distance formula:
Substitute the coordinates and calculate:
The distance is AB = 10 units
b) Use midpoint formula and find x and y- coordinates of this point:
and 
Substitute coordinates and find the midpoint:
and 
The midpoint is (2, 6)

Answer:
Item (D)
Step-by-step explanation:
In the stratified random sample we would divide our population into homogeneous groups / strata and then we randomly select the individuals in each group / stratum.
In general, when comparing with the simple random sample, we realize that stratified random sampling has the advantage of increasing accuracy and decreasing variability.
In the question, we have two strata: female students and male students. On each one of the strata, a random sample of 25 names was made in the list.
